Grundfos Submersible wastewater pump DP10.50.15.E.2.50B

GRUNDFOS DP AUTOADAPT pump is a portable pump for both domestic and industrial applications.
The pump has a multi-vane, semi-open impeller for 10 mm free passage and is suitable for pumping
• drainage and surface water
• groundwater
• industrial process water without solids and fibres.
The compact design makes the pump suitable for both temporary and permanent installation.
The pump has an intermediate oil chamber pre-filled with non-toxic special oil.
The pump is fitted with a cable plug for easy dismantling. This plug is hermetically sealed with polyurethane to
prevent water from penetrating through the cable into the motor.
A clamp between pump housing and motor ensures easy and safe dismantling and assembly. Inspection can be
done in the field without any special tools.
The pump is fitted with a double shaft seal in the unique cartridge design. This makes it easy to replace the shaft seal
very quickly in the field without any special tools. It also eliminates the risk of faulty installation.
The motor is insulation class F and has long-life, deep-groove, greased-for-life ball bearings.
The pump has R 2 discharge port and is ready for installation either free-standing or on an auto-coupling system.
The Grundfos DP AUTOADAPT pumps incorporate a controller, sensors and motor-protection. They only need to be
connected to the mains supply.
If several pumps are installed in the same tank, the control logic incorporated in the pump will ensure that the load is
distributed evenly among the pumps over time.
• Alarm relay output.
The pump incorporates an alarm relay output. NC and NO are available and can be used as
required, for example for acoustic or visual alarms.
• Random start delay in case of general power shutdown.
• The pump does not start unless the phase sequence is correct.
• Self-calibration after each pump cycle.
• Anti-seizing system.
The anti-seizing system start the pump at programmed intervals to prevent the impeller from seizing up. This function
will overwrite the dry-run sensor for non EX versions.
The Grundfos CIU unit can be connected permanent or temporarily for changing the pre-setting, further settings or
read out from the logging and operation parameters like no. of starts and operating hours.
